(Reuters) - Wall Street surged on Monday, helped by a robust rally in oil prices that lifted recently crushed energy stocks, including Chevron and Schlumberger.

As it has for months, Wall Street followed the lead of global oil prices in a trend that has left the S&P 500 down 5 percent so far in 2016, following a partial recovery last week.

Monday's stock gains were as broad as they were strong, with all 10 major S&P sectors finishing higher, but investors shell-shocked by this year's market turbulence remained wary.

"You still have concerns about China and where growth goes there, and that's why you're still going to have this volatility," said Kurt Brunner, portfolio manager at Swarthmore Group in Philadelphia. "We're still going to have considerations about heavily indebted energy companies going into default."

U.S. crude prices settled up more than 6 percent but still remained around decade lows, while prices of industrial metals such as copper and zinc rose as investors worried about potential shortages.

The Dow Jones industrial average <.DJI> jumped 1.39 percent to end at 16,620.66 points. The S&P 500 <.SPX> gained 1.45 percent to 1,945.5 and the Nasdaq Composite <.IXIC> added 1.47 percent to 4,570.61.

The S&P energy sector <.SPNY> rose 2.23 percent, boosted by Chevron's <CVX.N> 2.68 percent increase. Shares of oilfield services provider Schlumberger closed up 2.06 percent.

The materials sector <.SPLRCM> rose 1.87 percent. Alcoa <AA.N> and Freeport-McMoRan <FCX.N> were the biggest influences, both surging over 13 percent.

Recent turmoil in global markets and macroeconomic uncertainty has left investors split over whether the U.S. Federal Reserve will raise interest rates this year.

Among S&P 500 companies, there have been 75 negative EPS pre-announcements for the first quarter, compared to 16 positive pre-announcements, according to Thomson Reuters I/B/E/S.

After the bell, Fitbit <FIT.N> dropped 15 percent after the fitness tracker maker's first-quarter profit forecast badly missed analysts' expectations..

UnitedHealth <UNH.N>, Anthem <ANTM.N>, Humana <HUM.N>, Aetna <AET.N> and other insurers gained after the U.S. government proposed raising payments to health insurers who offer Medicare Advantage health benefits to elderly and disabled Americans.

UnitedHealth was up 3.05 percent, providing a major boost to the Dow.

Shares of Aerospace component suppliers Honeywell International Inc <HON.N> fell 1.95 percent and United Technologies Corp <UTX.N>, a Dow component, rallied 4.69 percent after it was reported the two have held merger talks.

Advancing issues outnumbered decliners on the NYSE by 2,389 to 676. On the Nasdaq, 1,974 issues rose and 829 fell.

The S&P 500 index showed 19 new 52-week highs and one new low, while the Nasdaq recorded 38 new highs and 35 new lows.

About 7.1 billion shares changed hands on U.S. exchanges, below the roughly 9.1 billion daily average for the past 20 trading days, according to Thomson Reuters data.
